FIFTH-WHEEL 'SPECIFICATION forming part of Letters.

Application filed January 8, 1881. (Model.)

Be it known that we, THOMAS J. MAGNER and CHARLES L. THOMAS, ofHornellsville, in the county of Steuben and State ot' New York, haveinvented a new and Valuable Improvement in Fifth-Wheels for Vehicles;and we do hereby declare that the following is a full, clear, a-nd exactdescription of the construce, reference be ing had to the annexeddrawings, making a part of this specication, and to the letters andfigures of reference marked thereon.-

Figure l of the drawings is a front view. liig. 2 is a section taken thelength of the device. Fig. 3 is a plan view.

This invention relates to fifth-wheel connections for vehicles.

The invention consists `in the construction hereinafter described `andclaimed.

In the drawings hereto annexed, Ais the front axle, supporting' on itstop the lower member, B, ofthe fifth-wheel connections. This member Bconsists of a bar, C, having at its ends the circle-bars b b on top, andthe 'perforated lugs c c depending,r from said ends, and at its middlethe lower fi. til-wheel plate, D, having the perforated lugs d xtenliugdownward, and a central boss, d', projecting upward, said boss having ahole, d2, therethrough countersunk below at d3. This member, asdescribed, is to be cast in one piece. It is seated upon the top of axleA, the latter itting snugly between the depending lugs, and bolts arepassed through said lugs, and held below by tie-plates e and nuts e',the heads of said bolts being countersunk into tops of circle-bars b band lower i'th-wheel plate, D;

The upper member, F, of the fifth-wheel connections consists of a bar,Gr, similar to bar C, having at its ends, on the lower side, circle-barsff, tting and corresponding with circle-bars b b of the lower member,fins g g, projecting upward at said ends, and midway between these pinsa hole countersnuk below, at its middle, fifth-wheel plate, H, havingcentral perforation, h, corresponding to and to receive central boss,d', of the lower plate, D, having a perforated 1ug,h, projectingforward, and the arm I backward and downward, to be attached to thereach, fins g3 g3, projecting upward at the uab-Wheel upon the lowerside, the upper FOR VEHICLES.

plate H, and ribs K K, midway between such plate and the circle-bars,terminating at each side in the perforated lugs 7c lc. This member, asdescribed, is to be cast in one piece. The bolster or head-block L isSeated thereon between the iins and lugs described, tting snugly, and isheld by bolts M M passing through the ends of the b olster and holes iubar G.

The perforations in lugs dd are countersunk at the top, and passingthrough said perforations, with heads resting in the conntersinks, arebolts N N, tting close on each side of the axle, and held below the sameby tie-plate N and nuts n a. Projecting downward from the middle, andintegral with said tie-plate N', is a stud, P, having collar p andreduced screw-threaded end p.

R is a brace-arm, attached to the under side of the reach, correspondingto arm I. This arm extends under the axle, and has a perforation, r, atits end, and another, rf, where stud P comes. This stud passes throughperforaperforation r. S is a bolt passing through perforated lug h' andperforation r of arm R.

T is the king-bolt, its head resting in couiltersinlrdet-holedz, itsbody t passing through said hole, said body being round where it restsin the boss d', and up through the bolster L, where it is made angular,and said bolt being held at top by nut t'.

The bolts N N, clasping the front axle, take the place of thecheek-pieces" of the ordinary clip king-bolt, and, together with thekingbolt T, supply the place of said clip kingbolt. The central boss,d', and the swivel-connection of the stud l) with arm R, form theturning-[Join ts in cramping. The king-bolt, being held rigid by itsangular portion inthe bolster, turns by its round portion within thecentral boss.

V V are the clips for holding the the bolster, their ends being Insteadof using only one from the reach to the upper fifth-wheel plate, we mayuse two such bars running to the plate, or to the bar Gr when used for abuggy.

Instead of using the bolt S, the arm R may spring to held in lugs 7c k.

l. The lower fth-wheel plate, D, having perforated lugs d d and centralperforated boss, d', bolts N N, tie-plate N', having stud P, with collarp and screw-threaded reduced end p', and upper fifth-wheel plate, H,having central perforation, h, in combination with king-bolt T, havingits body round below and angular above, substantially as and for thepurpose described.

2. The lower member of the fifth-wheel 'connection, consisting of bar C,circle-bars b b, perforated lugs c c, lower lifth-wheel plate, D, havingperforated lugs CZ d and perforated central boss, d', all made in onepiece, in combination with the upper member, consisting of' bar G,circle-bars ff, hns g g, upper fifth- Wheel plate, H, having centralperforation, la, perforated lug h', and arm I, tins g3 g3, and
